Cartel gunmen left behind five dismembered bodies along with a threatening message in the most recent wave of gruesome killings that has shaken up the Mexican coastal state of Veracruz.

According to cartel messages and banners left behind at multiple crime scenes, the uptick in violence is tied to a territorial dispute between the Los Zetas drug cartel and Cartel Jalisco Nueva Generacion (CJNG).

On Tuesday early morning, authorities responded to a rural community near the town of Amatlan de los Reyes in connection to a gruesome discovery, Mexico’s Proceso Magazine reported.

At the scene, authorities found severed body parts from five separate bodies that had been placed next to two signs placed by the CJNG issuing threats to the Los Zetas cartel.

On Sunday, shortly after midnight, a team of cartel hit men pulled up to a night club in the city of Xalapa and began wildly spraying gunfire into the club. The attack injured more than a dozen people and killed five victims, Proceso Magazine reported. Also in Veracruz, a team of gunmen carried out another shooting at a bar in the city of Orizaba. In that case, the gunmen went inside and fired at two men, killing at least one.
